This patent date was seen on a Gardner No. 20 20-inch disk sander."One of the objects of the invention is to provide in a disk grinder a work table so mounted that it may be tilted at various angles without thereby changing the relation of the inner edge of the table to the disk. In prior machines when the table was tiled, the inner edge of the table moved away from the disk, and further means had to be provided to return the inner edge of the table into proper relation to the disk, since it is important, especially in wood working, that the work be supported as close as possible to the point where grinding is taking place. Another object of the invention is to support the table in such a way that it may be quickly moved entirely off the face of the wheel to permit of conveniently attaching an abrasive sheet to the face of the disk. A further object is to support the table in such a way as to afford free space for the work over the entire surface of the wheel."
